Visual ringer

ABSTRACT

Embodiments of the disclosed invention include an apparatus, method, and computer program product for providing a larger display area for viewing pictures and/or videos on a communication device. For example, in one embodiment, a communication device is disclosed comprising a plurality of display components for displaying an image that covers a plurality of sides of the communication device. In certain embodiments, a user specified image is displayed in response to receiving an incoming call for providing a more visible indicator for alerting the user of an incoming call.

BACKGROUND OF THE INVENTION

The disclosed embodiments are related to communication devices and, in particular, to providing a user customizable visual indicator of an incoming call.

Communication devices have generally provided two types of visual indicators. One type is a small light-emitting diode (LED) that blinks to inform a user of an incoming call or a missed call. The other type of visual indicator is displaying a caller identification or image on a display screen associated with the communication device to inform a user of an incoming call. However, display screens associated with communication devices are generally small and face only one direction, thus, a user may not notice a visual indicator of an incoming call. For instance, if the communication device is far away and facing up, the user may not hear the ringtone nor notice the visual indicator. Similarly, if the device is in silent mode and/or is accidently placed facing down, the user may not notice an incoming call.

Accordingly, certain of the disclosed embodiments seek to/provide solutions to one or more the above problems associated with visually notifying a user of an incoming call.

SUMMARY

Embodiments of the disclosed invention include a system, method, and computer program product for providing a visual indicator of an incoming call on a communication device. As referenced herein, an incoming call may include a voice call, a text message, and/or an e-mail message. For example, in one embodiment, a communication device is disclosed having one or more organic light-emitting diode (OLED) displays covering the entire exterior portion of the communication device. In addition, the communication device includes circuitry for connecting the one or more organic light-emitting diode displays to a processing component. The processing component is configured to display images on the one or more organic light-emitting diode displays to generate a composite image covering the entire exterior portion of the communication device. For instance, in one embodiment, the communication device may include logic for displaying a specified image on the one or more organic light-emitting diode displays in response to receiving an incoming call.

In addition, in some embodiments, communication interface 105 may support wireless data communications via an IP network, such as, but not limited to, the Internet.

In certain embodiments, communication device 100 may include caller identification logic 107 for determining the phone number of a calling device. As referenced herein, logic is defined as hardware, software, and/or a combination thereof. In some embodiments, caller identification logic 107 may also decode a received subscriber calling name associated with the calling device. Caller identification logic 107 presents the caller identification information on a display of communication device 100.

Additionally, in some embodiments, communication device 100 may include configuration logic 140 for enabling a user to configure the features and functions associated with communication device 100. For instance, configuration logic 140 may include logic for configuring the power modes of communication device 100, updating telephone numbers and address book information, and/or selecting a ring tone.

In addition, as will be further described, in some embodiments, communication device 100 may include image selection logic 150 for selecting an image, sequence of images, and/or video file that may be displayed on one or more peripheral displays 170. For instance, in one embodiment, peripheral displays 170 comprises a plurality of peripheral displays (D1-Dxx) that cover the entire exterior portion of the communication device. For example, in one embodiment, peripheral displays 170 comprises six display units, one for the top surface, one for the bottom surface, and one on each of the four lateral surfaces of communication device 100. In other embodiments, peripheral displays 170 may comprise of a flexible display component that wraps around one or more sides of communication device 100.

In some embodiments, peripheral displays 170 may comprise a number of display units corresponding to the number of individual components of communication device 100. For instance, in one embodiment, communication device 100 may include a set of raised keys, such as, but not limited to, a numbered keypad and/or a QWERTY style keyboard. In these embodiments, each individual key may be layered with a separate display unit. In some embodiments, a display unit may consist of a single pixel. For instance, as will be further described, in a preferred embodiment, an OLED display may be printed or layered on top of each component.

Additionally, in some embodiments, communication device 100 may include display logic 160 comprising pixel coordinator 162 and image mapper 164 for displaying the selected image on peripheral displays 170 to cover the exterior portion of communication device 100 with a selected image. For instance, in one embodiment, pixel coordinator 162 determines the placement/arrangement of the pixels associated with each peripheral display and stores the pixel coordinates in memory. A pixel (or picture element) is the smallest item/block of information in an image. Image mapper 164 uses the pixel coordinates associated with each peripheral display for mapping a selected image onto peripheral displays 170 to create an image that spans across the multiple displays.

In addition, in certain embodiments, communication device 100 may include touch screen logic 166 for detecting a user's touch. For instance, in one embodiment, peripheral displays 170 may display one or more control keys in response to detecting a user's touch, or may turn off peripheral displays 170, and/or may automatically answer an incoming call.

Further, in some embodiments, communication device 100 may include a motion sensor 180.

With reference now to FIG. 2A, an external embodiment of communication device 100 is depicted in accordance with certain embodiments. In the depicted embodiment, communication device 100 comprises of a housing 200, a set of raised numbered keys 202, a call button 204, an end-call button 206, a set of control keys 208, and a display screen 210. In accordance with certain embodiments, each component may be layered with a separate display unit during the manufacturing process. For instance, as will be further described, in one embodiment, each individual number key within the set of raised numbered keys 202 may be respectively layered with a separate display component D4-D15. In addition, call button 204 and end-call button 206 may be respectfully layered with separate display components D23 and D24. Similarly, the set of control keys 208 may be respectfully layered with separate display components D2 and D22. Additionally, in certain embodiments, display screen 210 may be the same type and/or a different type of display component as the other components of communication device 100.

In some embodiments, housing 200 may include one or more display components, such as, but not limited to, display component D3 and D16-D20. For example, display component 3 (D3) may be layered on the front surface of communication device 100. Display components 16 and 18 (D16, D18) may be respectively layered on each side surface of communication device 100. Display components 17 and 19 may be respectively layered on the bottom and top surface of communication device 100. Additionally, display component 20 (D20) may be layered on the back surface of communication device 100. Alternatively, in other embodiments, housing 200 may be layered with a wrap around display component that covers one or more surfaces.

Display components 1 through 24 may utilize any type of display technology including, but not limited to, liquid crystal display (LCD), LED, OLED, plasma, and/or other types of suitable display technologies for generating an image. Liquid crystal display consists of two layers of transparent polarized material. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through the individual crystals, which allow the crystals to pass or block light to create images. On the other hand, plasma technology employs the burning of phosphors to generate an image. An electrophoretic display forms visible images by rearranging charged pigment particles using an applied electric field.

In a preferred embodiment, communication device 100 utilizes organic light emitting diode (OLED) technology displays for generating an image. OLED is a light emitting diode whose emissive electroluminescent layer is composed of a film of organic compounds. OLEDs emit light through a process called electrophosphorescence. A significant benefit of OLED displays is that OLEDs do not require a backlight to function. Additionally, OLED displays draw far less power than other types of display technology, and therefore, can operate longer on the same charge. Because there is no need for a backlight, display components 1 through 24 can be very thin. For example, OLED displays may be as thin as 500 nanometers in thickness or about 200 times thinner than human hair.

FIG. 3 depicts an embodiment of an OLED display 300 the may be utilized by communication device 100 for displaying an image that spans the entire exterior portion of communication device 100. Like an LED, OLED display 300 is a solid-state semiconductor device. OLED display 300 comprises layers of organic material 330. For example, in one embodiment, organic material layers 330 may include an emissive layer and a conducting layer. The emissive layer is made of organic plastic molecules that transport electrons from cathode 350 for generating light. For example, in one embodiment, polyfluorene may be a polymer used in the emissive layer. The conducting layer is made of organic plastic molecules that transport “holes” from anode 320. In one embodiment, polyaniline may be a polymer used in the conducting layer. Anode 320 generates electron “holes” by removing electrons when a current flows through the device. In contrast, cathode 350 is used to inject electrons when a current flows through the device. The current is received from circuitry that connects cathode 350 to printed circuit board 102 and/or other components of communication device 100. Additionally, in some embodiments, organic material layers 330 may comprise three or more layers of organic material. The additional layers may be utilized to help transport electrons from cathode 350 to the emissive layer. Further, in some embodiments, OLED display 300 may include a substrate component 310. Substrate component 310 may be used to provide support for the components of OLED display 300. In some embodiments, substrate component 310 may be clear plastic, glass, and/or foil.

In certain embodiments, OLED display 300 may be either a passive-matrix OLED (PMOLED) or an active-matrix OLED (AMOLED). Passive-matrix OLEDs have strips of cathode, organic layers, and strips of anode. The anode strips are arranged perpendicular to the cathode strips. The intersections of the cathode and anode make up the pixels where light is emitted. External circuitry applies current to selected strips of anode and cathode for determining which pixels get turned on. The brightness of each pixel is proportional to the amount of applied current.

An active-matrix OLED may include a TFT matrix 340, as depicted in FIG. 3. TFT matrix 340 is a thin film transistor (TFT) array that forms a matrix. TFT matrix 340 is the circuitry that determines which pixels get turned on to form an image. AMOLEDs consume less power than PMOLEDs because the TFT array requires less power than external circuitry. In addition, AMOLEDs have faster refresh rates suitable for video.

Additionally, in certain embodiments, OLED display 300 is a transparent OLED. For example, in one embodiment, OLED display 300 may include only transparent components (substrate, cathode and anode) and, when turned off, OLED display 300 is substantially transparent. For instance, in one embodiment, a transparent OLED display 300 may be layered on top of a set of function keys (e.g., number keys) of communication device 100 for enabling a user to see the printed function and/or number (e.g., talk, 1, 2, 3, . . . ) on the function keys when OLED display 300 is in an off mode.

Further, in a preferred embodiment, OLED display 300 utilizes foldable OLEDs. Foldable OLEDs have substrates made of very flexible metallic foils or plastics. Foldable OLEDs are very lightweight and durable. Therefore, by utilizing foldable OLEDs, damage to OLED display 300 may be reduced.

OLED display 300 may be layered on communication device 100 using one or more known or later developed techniques. For example, in one embodiment, OLED display 300 may be layered on communication device 100 using vacuum thermal evaporation. Vacuum thermal evaporation utilizes a vacuum chamber to gently heat/evaporate the organic molecules. The organic molecules are then allowed to condense as a thin film. Similarly, OLED display 300 may be manufactured using organic vapor phase deposition. In a preferred embodiment, OLED display 300 is layered on communication device 100 using inkjet technology to spray the OLEDs onto communication device 100 or components thereof similar to spraying ink onto a piece of paper.

With reference now to FIG. 4, an embodiment of a process 400 is presented in accordance with certain embodiments for providing a visual indicator in response to receiving an incoming call to communication device 100. Process 400 begins, at step 402, by receiving a user selection of an image that will be displayed on a plurality of displays that spans a plurality of sides of a communication device in response to receiving an incoming call for providing a visual indicator to notify a user of the incoming call. In one embodiment, the image may be a still image, a sequence of images, and/or a video file. As referenced herein, the phrase “a plurality of sides” means two or more sides that face different directions.

In some embodiments, process 400 may, at step 404, associate the selected image with a user specified caller identifier. Additionally, in certain embodiments, the image may be stored locally on communication device 100 and/or may be stored on a remote network device. For example, in certain embodiments, communication device 100 may communicate with a network device such as, but not limited to, a Web application server for enabling a user to link a caller ID with a particular social networking website user account. In these embodiments, communication device 100 may retrieve a profile image of the caller from a social networking website for displaying the profile image in response to receiving a call from the caller. In certain embodiments, communication device 100 may store the profile image locally and may periodically communicate with the social networking website to update the profile image. In other embodiments, communication device 100 may retrieve the current profile image in real-time from the social networking website in response to receiving a call associated with the user specified caller ID. In other embodiments, a user may select any type of image, sequence of images, and/or video that is displayed in response to receiving an incoming call.

At step 406, the process determines the mapping coordinates for mapping the image onto the plurality of displays associated with the communication device. For instance, in one embodiment, the process may determine the pixel coordinates associated with each display component and utilize that information for determining the mapping of the image. When the process receives an incoming call matching the caller identification at step 408, the process, at step 410, presents the image on the plurality of displays of the communication device for providing a visual indicator of the incoming call.

In one embodiment, the image may span/wrap around the entire exterior portion of communication device 100. In other embodiments, the image may appear only on non-downward facing sides of communication device 100 to conserve energy and for properly displaying the image only on viewable sides. For instance, communication device 100 may include an orientation sensor or touch sensor for determining a downward facing side. A downward facing side is any side that is in contact with a surface. For example, if communication device 100 is placed on a desk, the side of communication device 100 in contact with the desk is a downward facing side. The downward facing side of communication device 100 may change depending on how communication device 1000 is oriented.

In some embodiment, the process, at step 412, may determine whether a user picks up communication device 100 using a touch sensor and/or a motion sensor. For instance, in certain embodiments, communication device 100 may comprise flat touch screen panels such as depicted in FIG. 6A. In these embodiments, process 400, at step 418, may display a set of control keys, such as, but not limited to, an answer button for enabling a user to answer the incoming call. In other embodiments, the process, at step 420, may have been configured to automatically answer the incoming call in response to detecting a user. Optionally, in certain embodiments, the process may, at step 416, display a different image in response to the incoming call being routed to voicemail. Additionally, in certain embodiments, the process, at step 414, may turn off the displays in response to detecting the presence of a user, with process 400 terminating thereafter.

FIG. 5 illustrates an embodiment of communication device 100 in accordance with the disclosed embodiments. In the depicted embodiment, an image and/or video of a fire is selected as a visual indicator image. In response to receiving an incoming call, communication device 100 displays the flame image and/or video on the plurality of display components to create an image that communication device 100 is covered in flames. In some embodiments, the flame image may be generated by communication device 100 by rapidly displaying a sequence of flame images that produces a visual effect of a real fire. In other embodiments, communication device 100 may include logic for modifying the flame image to produce a dynamically moving image. For instance, in one embodiment, communication device 100 may utilize the stored pixel mapping data to dynamically turn particular pixels on and/or off to generate of a visual effect of a moving flame. In one embodiment, in response to detecting a user's presence of (e.g., a touch and/or movement), communication device 100 turns off the display components revealing the standard components of communication device 100.

In other embodiments, communication device 100 may include only flat surfaces. For example, FIG. 6A depicts an embodiment of a communication device 600 in accordance with the disclosed invention. In the depicted embodiment, communication device 600 may comprise of one or more touch screen display components. For instance, in one embodiment, communication device 600 may comprise of six display components labeled D50-D60. In this embodiment, each display component is oriented to display an image on a particular side of communication device 600, as depicted by the direction of the arrows respectively associated with D50-D60. In other embodiments, communication device 600 may comprise a display component that covers one or more sides of communication device 600. Additionally, in certain embodiments, communication device 600 may include logic for presenting a touchable keypad and/or other information for enabling a user to utilize communication device 600.

FIG. 6B illustrates the flame image and/or video presented on communication device 600. In one embodiment, the image is displayed in response to receiving an incoming call. Of course, in certain embodiments, communication device 100 and/or communication device 600 may simply utilize one or more of the plurality of display components for providing a larger display area for viewing pictures and/or videos. Additionally, in certain embodiments, different images may be simultaneously displayed on one or more display components and/or sides of communication device 100/600. For example, in one embodiment, communication device 100 may display a video on a front side of communication device 100, display a stock ticker on one side of communication device 100, and display a headline news ticker on the other side of communication device 100.

Accordingly, the disclosed embodiments provide a system and method for providing a more visible indicator of an incoming call on a communication device.
